MEANS FOR PROTECTING-'RIVER-BANKS.

Specification of Letters Patent.

Patented Oct. 3, 1911.

Application filed December 10, 1910, Serial No. 596,627.

To all whom it may concern;

Be it known that I, ALBERT GREEN, a citizen of the United States,residing at WVestalton, in the county of St. Charles and State ofMissouri, have invented new and useful Improvements in Means forProtecting River-Banks, of which the follow ing is a specification.

This invention relates to a means for protecting river banks fromcorrosion and for diverting the channel of streams.

The object of the invention is to accomplish the proper protection ofland on either stream bank with simple, efficient and inexpensive means.

Further objects of the invention will appear as the following specificdescription is read in connection with the accompanying drawing, whichforms a part of the present application, and in which Figure 1 is a topplan view. Fig. 2 is a vertical section through a portion of the riverand river bed taken on the line 2-2 of Fig. 1.

Referring more particularly to the draw ing, 1 represents the stream, 2the bank to be protected, the present channel of the river beingindicated by the dotted lines m. In order to divert the channel to apoint closer to the island 3 or to a point more central in the stream, arow of piles 4 is driven at intervals extending outwardly from the shoreinto the river as far as is desired and these piles have their topsarranged slightly above the bottom 5 of the river. Immediately below therow of piles 4 and separated therefrom a suitable distance is a secondrow of piles 6 arranged in a similar manner and having their topsprojecting above the water. Each pile of the series 4 is connected withits coacting pile in the series 6 by a cable 7 and this cable 7 in eachinstance lies upon the bottom of the river. Cables 8 are connected toeach of the piles in the series 4 and extend slightly above the bottom 5and are connected at their opposite ends tothe tops of the piles of theseries 6, as shown at 9. The cables 7 are simply used as reinforcingmembers while the cables 8 are adapted to receive the drift or debriscarried down the river and collect the same until it is sufiicientlyheavy to sink to the bottom and form a jetty extending from the shoreinto the stream. When this etty is of sufiicient density, a sand bar isformed back of the same and the bank 2 properly protected and thechannel diverted to a point farther away from the shore.

In practice the series of piles 4 and 6 are arranged so that each pilefrom the shore pile outwardly is arranged slightly farther upstream thanthe preceding pile, thus making the series as a unit slightly inclinedupstream.

Having thus described the invention, what I claim as new is 1. Means forprotecting river banks comprising a series of piles driven into theriver bottom and extending slightly thereabove, said piles beingarranged with the offshore pile of the series farther up the stream thanthe shore pile of said series, a second series of piles extending abovethe water and arranged parallel with the first series, reinforcingcables connecting said piles and debris supporting cables connected tothe first series and to the top of the second series.

2. Means for protecting river banks comprising a series of piles driveninto the river bottom and extending slightly thereabove, a second seriesof piles separated from the first series and extending above the water,said second series being arranged parallel with the first series,reinforcing cables connecting said series of piles, and lyingsubstantially on the bottom of the river, and debris supporting cablesconnected to the first series and to the top of the second series.

In testimony whereof I aflix my signature in presence of two witnesses.

ALBERT GREEN.
